Description & summary/Desgin Process
Here is a description of the fields:
Civil Engineering: This is field of engineering designs and builds infrastructure both publicly and privately. They are essential to the growth and maintenance of civilizations. One of the main tools of their trade is software, namely simulation software. This allows them to get accurate models of the forces acting upon their works, ranging from bridges and skyscrapers to aqueducts and dams. There is also a wide range of sub disciplines like Geotechnical, Transportational, Structural, and Water Resources Engineering.
Building Science: This is the science used to describe the natural effects that occur in buildings. It uses a combination of Physics and Architecture to do this. Additional studies include lighting, the way sound effects a room, and building temperatures. These studies are centered around the inhabitants and what the space would be used for. It allows for the optimization of buildings both new and old.
Design Process:
We started this week's project by testing out BridgeDesigner and the ModelSmart3D program. After we were familirized with both programs, we assigned different roles to each group member to achieve our main goal.
In the bridge building process, we first began by making a standard truss bridge with the basic specifications for the bridge. After playing around with the bridge and the different desgins of the bridge, we eventaully made the bridge heigher. This meant the member in the middle would be the lengthiest one. This helped to lower the cost of the bridge becuase we were able to make some of the memebrs slimmer and therefore use less material.
After we figured this out, we just adjusted each specifc member in order to ensure they were under the compression/tnesion requirements and we tested each one to see if they could be changed to lower the costs. When we had all the requirements down we tested the bridge making sure that it worked and increased/decreased the sizes of the members depending on which ones needed it the most.
Next we moved to SmartModel3D in which we decided to keep the same shape of the bridge. We only had to add more joints and members since this bridge was longer and we had to make the size of the memebrs larger. When we ran the analysis we fixed the memebrs that needed it the most making out bridge stronger until we were able to sustain the maximum capactiy of 1074.2 lbs.
After we had the 3D model down, we then passed this design into TinkerCad in order to 3D-print it and after a couple of adjustments our design was ready to print.
